| 摘 要： | 土地利用/覆被变化及其驱动机制研究是研究全球变化的前沿及热点问题之一。我国农村居民点分布广、数量多,农村居民点用地规模是城镇建设用地规模的6倍以上,加之农村居民点周边多为优质耕地,对耕地资源减少的威胁甚于城镇。当前我国土地资源利用的一个突出问题就是在农村人口非农化的过程中,农村居民点用地规模并没有随着城市化的发展而减少,甚至部分地区出现了快速增加的势头,加强农村居民点用地变化及其驱动机制研究,为合理调控用地提供科学依据,便具有了重要的理论与现实意义。本文首先从理论上论述了农村居民点用地变化的驱动因素,随后以江汉平原典型地区仙桃市为例,采用1996年~2004年的土地变更数据和社会经济统计数据,分析了农村居民点用地变化特征,并进一步运用多元统计中的因子分析法和多元回归模型,对引起农村居民点用地规模变化的社会经济驱动因子进行了定量研究。研究结果显示,仙桃市农村居民点用地总量呈递减趋势,但仍然呈粗放利用状态,经济增长和城市化的发展、科技进步以及政策制度是仙桃市农村居民点用地变化的主要驱动因子。

| Abstract: | The research on land use/cover and its driving force is one of the main research subjects worldwide.The land use for rural residency is an important type of land use because of its quantity and scale,which is more than 6 times of the scale in city and town.Moreover,most of the rural settlements surround by the high quality cultivated land,so the sprawl of rural settlements is more threatening to the cultivated land than the extension of city and town.One of the outstanding problems of land use is that the scale of rural settlements has not been decreased with the urbanization.In fact,it is increasing quickly.So the study on the changes of land use rural residency and their driving forces is important for protecting cultivated land and accelerating the new rural construction and rural development theoretically and realistically.First of all,the driving forces of land use change for rural residency were explained in the paper.Natural factors and socio-economic factors,and the socio-economic factors would be paid more attention because the effects of natural factors have little influence on rural residential land within a relatively short time.Then,the Xiantao City in Hubei province was taken as an example to study the changes of land use for rural settlements and the driving forces based on the land conversion data and socio-economic statistic data from 1996 to 2004.The results showed that the quantity of rural residential land has decreased 172.59 hm~2 for the past 8 years in Xiantao City,and the land use intensity was low.Per capital land area for rural settlement was 171.76m~2,exceeding the average criterion of 21.76m~2 in China.By the factors analysis,the main driving forces of land use for rural settlements were analyzed,including the economic development and urbanization,the development of science and technology and the policy factors.The regression method was set up based on the main three driving forces of the rural residential land use changes.At the end,some valuable conclusions and recommendations were put forward based on the analysis aforementioned. |
